Dynamic Executors of Bacterial Signals: Functional Versatility and Regulatory Networks of c-di-GMP Effectors

Biomolecules
Cyclic di-GMP (c-di-GMP), a universal second messenger in bacteria, orchestrates a wide array of essential life processes. Its intracellular dynamics are meticulously regulated by diguanylate cyclases (DGCs) and phosphodiesterases (PDEs), ensuring ...

Dual Covalent Targeting of STING Cysteines 292/309 Disrupts Functional Oligomerization and Enables Potent Antagonist Development

Advanced Science, EarlyView.
We report a rational design strategy for STING antagonists by dual covalent targeting of Cys292/309 in its C‐terminal domain, directly preventing functional oligomerization. Through covalent warhead repurposing, we identified P005091 and revealed its unique dual‐cysteine mechanism.

Endo-S-c-di-GMP Analogues-Polymorphism and Binding Studies with Class I Riboswitch

Molecules, 2012
C-di-GMP, a cyclic guanine dinucleotide, has been shown to regulate biofilm formation as well as virulence gene expression in a variety of bacteria. Analogues of c-di-GMP have the potential to be used as chemical probes to study c-di-GMP signaling and ...

EEPD1 Inhibition Unleashes Antitumor Immunity in Colorectal Cancer by Activating the cGAS‐STING Pathway

Advanced Science, EarlyView.
In colorectal cancer, high expression of the DNA repair protein EEPD1 correlates with immune exclusion and poor prognosis. This study demonstrates that EEPD1 depletion induces genomic instability, leading to cytosolic DNA accumulation and subsequent activation of the cGAS‐STING‐type I interferon pathway. This cascade remodels the tumor microenvironment

Nanomedicine Meets Immunotherapy: Advancing Adoptive Cell Therapy with Nanoparticles in the Treatment of Cancer with Sustainability Perspectives

Advanced Science, EarlyView.
This review surveys nanoparticle‐based strategies to enhance adoptive cell therapy, particularly CAR‐T cell approaches, in solid tumor treatment. It describes how nanoparticles can improve tumor immunogenicity and T‐cell infiltration while reducing toxicity, and how they enable in vivo CAR‐T cell generation.

ESCRT‐Mimetic Nanodegrader Targets STING for Anti‐Inflammatory Therapy

Advanced Science, EarlyView.
A nanoplatform‐enabled targeted protein degradation strategy is presented to regulate aberrant STING signaling. STING‐ATTEC induces selective autophagic degradation of STING via formation of a STING–ATTEC–LC3 ternary complex, while the cationic FA‐LNP+ system enhances LC3 generation and targeted delivery. Together, this synergistic approach efficiently

Discovery of Novel c-di-GMP-Related Genes in Leptospira interrogans

Pathogens
Cyclic di-GMP (bis-(3′→5′) cyclic dimeric guanosine monophosphate) is a ubiquitous bacterial second messenger that regulates a wide range of cellular processes, including biofilm formation, motility, virulence, and environmental adaptation.

Albumin‐Bound STING Agonist Reprograms HSPCs to Antitumor Neutrophils Enhancing CD8+ T Cell Immunity

Advanced Science, EarlyView.
This study demonstrates that an albumin‐bound STING agonist (Nano ZSA‐51D) reprograms HSPCs to produce antitumor neutrophils with enhanced MHC I–mediated CD8+ T cell activation, thereby sensitizing tumors to α‐PD1 therapy. These findings highlight a strategy to target early hematopoiesis for shaping neutrophil fate and potentiating cancer immunotherapy.

Cyclic GMP protects human macrophages against peroxynitrite-induced apoptosis

Journal of Inflammation, 2009
Background Nitric oxide (NO) can be both pro- and anti-apoptotic in various cell types, including macrophages. This apparent paradox may result from the actions of NO-related species generated in the microenvironment of the cell, for example the ...
